WATCHIVIAKERS TOOL.

To @ZZ whom/t may concern.-

Beit known that'I, WILLIAM HELLBERG, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements inWatchmakers or Jewelers Tools; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

The object of the present invention is the provision of a tool for watchmakers which will combine in one organization means for removing andreplacing jewels in a watch movement from the smallest to the largestsize, an oiler and a cap-jewel setter, the latter being reversible topresent active ends of different diameters to accommodate difterentsizes of cap jewels. A hollow stake is provided and used in connectionwith the tool to receive the jewels and prevent them from becoming lostwhen removed from the bridge and other jeweled portions of the movement.

A further object of: the invention is a tool of the character describedwhich will be compact, easily manipulated, light and comprise a minimumnumber of parts consistent with the range and scope of the device.

The invention comprises a series of concentric tubular plungers placedthe one within the other, and a corresponding series of hand operateddevices for projecting the required plunger into operative position. Inthe preferred form of construction the plungers have a threaded portionand the plu nger operating devices are thumb nuts held and working inco-operative relation so that a rotation of the proper thumb nut willactuate and project into workin g position the plunger operativelyconnected with Ythe said thumb nut.

The improvement will be described more particularly'hereinafter andsetforth in the subjoined claims, and is illustrated in the accompanyingdrawings, in which- Figure 1 is a side elevation of the tool showing itin connection with the hollow stake, and the manner of applying the samefor removing jewels from their setting. Fig.Y 2 is a longitudinalsection of the tool on a larger scale. Fig. 3 is a side elevation of theseveral plungers separated and arranged in progressive order. Fig. 4 isa sectional detail showing'the manner of connecting the thumb nutstogether in series. Fig. 5 is a detail View of the thumb nut connectingspring; and Fig. 6 is a detail section of the cap jewel setter showingthe means of securing it on the grooved stem or projecting end of theinnermost plunger.

Similar letters and numerals referto corresponding parts in the severalviews.

The plungers 2, 3, 4, 5k and 6 are tubular and concentrically disposed,the one tting snugly within the other and arranged so that the Workingends will come flush or about in the same plane when all the plungersare moved in to their utmost limit. A pin or screw A passes laterallythrough openings in the sides of the plungers to prevent them fromturning independently of each other whereby when the proper thumb nut isrotated'the plunger having screw thread connectionY therewith willreceive a longitudinal movement which projects its working end beyondthe ends of the other plungers. The openings a, in the sides of theplungers 3, 4, 5 and 6 are elongated in the direction of the length ofthe plungers to admit of the plungers having a relatively longitudinalmovement, the pin a, limiting the movements of the plungers byengagement with the closed ends of the elongated openings. The pin orscrew A is'carried by or attached to the plunger 2. Thelatter may formthe handle, but being of steel which is easily corroded it is preferredto surround the same bya sleeve or casing 7 which is highly polished andfinished to enable the lingers to obtain a firm grasp thereon when usingthe tool. Each of the plungers except the outer plunger 2, has athreaded portion which enters a corre' spondingly internally threadedthumb nut. TheA plungers are of graduated lengths to correspond with therelative positions of the thumb nuts 8k, 9, lO and K11 which are placedend to end in a progressive series.

thumb nuts are of the same diameter and size to give a uniformappearance to the completed tool and are connected to preventlongitudinal separation or displacement. The

nut 1l has a neck b which tits Within the enlarged end ot' the nut 10.The opposing sides of the neck 11 and the walls of the nut 10surrounding the said neck have annular to grooves in coincidentrelation. An elliptical spring B is provided and interlocks with the twoannular grooves and secures the two nuts together without interferingwith their full rotary movements. The other thumb nuts 15 are securedtogether in precisely the same manner as the nuts 10 and 11.

The'lplunger 2,has spring arms c at the inner end which terminate inlateral extensions that spring outward and enter an annular 2o groovewithin the nut 11. Openings d are provided in the sides of the nut 11and opposite the inner annular groove and at diametrically oppositepoints so that when it is required to remove the plunger 2 from the nut11 a pronged instrument has its pointsthrust through the said openingsand against the enlarged ends of the spring arms c which have beenpositioned opposite the said openings d. By compressing the spring armsthe 3o enlarged ends thereof are cleared of the annular groove and theplunger can be easily withdrawn by pulling apart the nut and plunger.Each of the nuts 8, 9 and 10 have similar springs in the sides to admitof access to compress the interlocking springs B to permit of theirseparation when required.

The inner plunger G is extended to form a stem 12 which receives acap-jewel setter D and aslide E. The latter is similar in appear- 4oance to the thumb nuts and is connected by a pin or screw e with anoiler F which is adapted to slide within the inner plunger 6. The pin orscrew e passes through a slot f in the stem 12 which limits themovements of the oiler F. The oiler is a wire having a gold point toprevent poisoning the oil.

The cap-jewel setter D has its end portions of dierent area to adapt itto the setting of cap-jewels of different sizes, and is reversibly 5omounted on a stem 12, which is annularly grooved near the end to retainthe cap-jewel setter in place and prevent its being accidentallymisplaced. The intermediate enlargement has an annular groove in itsedge in which is seated aspring 13 one end of which is bent and enteredin an opening, the other end bearing on a headed stud d which is mountedin an opening in the said enlargement and moves radially therein. Theinner 6o end of the stud is rounded and is adapted to enter the annulargroove in the stem 12 and retain the cap-jewel setter in place thereon.

The stake G is hollow and has a broad base and is made of aluminum whichis light and of such a character as not to injure the jewels. Thecap-jewel setter is of the same metal to These i prevent marring orotherwise injuring the l cap-jewels. The stake being hollow receives thejewels as they are detached and prevents them from getting lost. Thetool is used in the ordinary manner. For large jewels the plunger 2 isused, the other plunger being Withdrawn from an operative or workingposition. For the smallest jewels the plunger 6 is projected into aworking position beyond the ends of the other plungers by rotating thenut 8. For operating on jewels intermediate and small and largest sizes,the proper plunger is projected by rotating the nut in connectiontherewith. The part D is used only when placing the cap-jewels in place.

Having thus described my invention, what l claim as new, and desire tosecure by Letters Patent, is

1. A watchmakers tool embodying in a single organized structure a seriesof jewel setters of graduated sizes, means for projecting the requiredjewel setter into working position, an oiler housed and protected by thejewel setters, means forbringing the oiler into operative position, anda cap-jewel setter supported by and forming part of the tool structure,substantially as specified.

5. A watchmakers tool comprising a series of tubular plungers arrangedthe one within the other, the relatively longitudinal movable plungershaving a threaded portion, a pin passing through elongated openings inthe plungers to hold them from independent rotary movement, and a seriesof thumb nuts, one for each plunger to project the required plunger intoworking position, substantially as described.

6. The combination with a series of concentric plungers having threadedportions, of a series of thumb nuts, the one having a neck portion toenter the enlarged end of the other, and an interlocking deviceprojected across the joint between the meeting parts of the nuts,substantially as described.
